The invention relates to a device and method for the defined longitudinal shifting of an adjusting device which rotates along in a drive shaft, along the center axis of the drive shaft. An embodiment of the invention comprises a rotating bearing runner having a wear resistant face and a stationary bearing carrier defining a plurality of cavities disposed annularly around the carrier. Further, instead of coating the SiO2 layer, a metal layer can be used to form a eutectic structure with the silicon substrate. Wire bonds are provided between the two different semiconductor dies in order to form circuit paths between the different first through third portions. A braking mechanism is coupled to the actuator.
