I don't know what surplus stores are like in your end of the world.  Out
here, there's a few that often have what you need:  An electric clutch.
I've also seen one improvised out of a solenoid and a small differential.
Just use the solenoid to block the differential's internal rotation.  It's
not very precise, but it works.  I've also seen a clutch that works on
direction of rotation (effectively, an analog ratchet).  You just have to
keep combing the parts bins and see what you come up with.
