Your second guess was correct. It's not just a wrench. It's listed as a Screwdriver/spanner on Lego.com: This part was also included in several sets in the Games line as a human tool to remove tiles from the dice. It's unclear (at least to me) whether this part was intended to be used for tile removal when it was introduced in 1979. Here's an example from ...
When your function (such as an extending crane boom) gets to one limit or the other, this clutch gear ratchets instead of binding up the motor and all the gears in between. ETA: Forgot the second question. It has appeared in many sets, most recently the Fairground Mixer.
Is it possible that you are thinking of this goblet (2343)? This part was fairly common, and it was introduced around 1985, so it was probably in your collection. 1x1 round plates attach securely to the top as shown in this lamp from the Pet Shop:
One possible solution might be to use one of the new 1x1 round plates with open studs and a Bar with Clip
In the case of 87609, the piece was first used in 2010 as part of the grill/bumper assembly for vehicles that were the standard 6 studs wide. Its length would appear to be a result of its original purpose. Its width also allows for attaching two rows of detail: 99206 showed up first in 2012. Its design allows for a more compact construction in ...
Just today I tried to use it quite successfully as an alternative to suspension springs. Right now I don't have it assembled so I can't post a screenshot, but the idea is to wind up the pullback motor then attach it to your construction with a cross axis from one side and beams from another and limit its moving with some details. If you are interested in how ...
Build a catapult with it. The catapult arm would be attached to the motor. Pulling the arm down will wind the motor
Once I built a hand-powered semi-automated screwdriver toy for kids. They needed to "charge it" first by rotating a gear and then push a button to release power. Then they could apply it to a crane or other models.
A conditional can perhaps be represented by a door that can be blocked from the other side, or maybe two doors, of which only one is blocked via a sliding brick. As for loops, I would represent them as conditionals with counters, by blocking a door with a set number of bricks and removing one brick per iteration. If you'd rather count upwards, then a fixed ...
I still have cups and 1x1 round bricks from the late 70's and I can ensure you these were never brickable like you suggest. In the 80's, another popular build from Lego was composed of a transparent cup on top of a transparent minight head. Here is a colored example of that build.
