One half of the claw coupling is screwed onto the rotating
flange plate at the motor. Via the elastomer ring that
serves for dampening, the torque is transferred to the other
half of the claw coupling that is screwed onto the drive
shaft. The drive shaft is connected to the intermediate gear
by means of a feather key.
