I dismantled the one from my 8475 because I was sick of the steering slightly
over-running when it centred up again.
It uses a quarter-gear a bit like the end of this bionicle piece:

And it makes electrical contact with a series of arcs etched on a circuit board
in a sort of binary pattern. From the range of arc sections it makes contact
with, the controller knows roughly what angle it's at. It then uses a small
motor to drive it to the left or right, until it detects it's in the right
position. But it's a bit of a slack mechanism, and the motor is prone to
over-running, so it's not very good at centering itself properly.
