An extension shaft that is rotationally symmetrical and has a driver is coupled to the actuating shaft. The extension shaft has a rotation-symmetrical bead and is embedded in the synthetic resin in a positive-fitting manner. The extension shaft also has an adjustment and protruding to the outside of the resin, and a surface which forms a separation layer toward the resin.
