  • a transmitter can be arranged in or on the second drive element (11).
  • the encoder reports the angle of rotation of the second drive element (11) to a sensor.
  • the second drive element (11) can also be driven mechanically without an encoder or the like.
  • the first drive element (9) and the second drive element (11) particularly preferably have a single-stage gear ratio.
