Describe the Suggestion

I want to suggest that you could make the wrench adjust the speed of the hand crank similarly to the way the creative motor works, however obviously not exceeding current speeds. It would be nice as well, if it could go into the negative, reversing the way it's turing by standard right-clicking.

If you were to move something like this

or this

you would need multiple gears to make it turn slower and all in all make the contraption attached to the wind bearing huge just for speed adjustment.

But this type of interface would be perfect for adjusting:

Additional Context

For certain aesthetic contrapations I would love to use the hand crank as a manual way to move/open something, but it is way to fast, which makes it hard to control and look ridiculous. Especially contraptions with a big radius that are attached to mechanical bearings can look crazy.

Since nothing about its current max. speed would change, it would only be for aesthetics. It could however, make big contraptions seem heavy and hard to turn or make it more similar to real live where one could just simply turn it slower.
