In a throttle valve actuator unit having a throttle valve neck that contains a pivotable throttle valve and having a drive chamber for receiving an electric drive mechanism for the throttle valve and for receiving an electric connection plug for a plug connection to a control unit, in order to reduce the production costs while maintaining the many customer-specific characteristics, the drive chamber is enclosed by a housing module, and the throttle valve neck is attached as a separate part to the housing module and secured thereto.

A measuring device for contactless detection of a rotational angle (&agr;) comprises a carrier plate ( ), made of soft-magnetic material, which acts as a rotor. Two segments ( ) separated by a slit ( ) are disposed in a plane parallel to the carrier plate ( ). Disposed on one of the segments ( ) is a short-circuit piece ( ), and all these parts are of soft-magnetic material. The short-circuit piece ( ) and the segments ( ) serve to guide the magnetic flux that is generated by a permanent magnet ( ) disposed on the carrier plate ( ). Since the short-circuit piece ( ) protrudes past the carrier plate ( ), or in a further feature the carrier plate ( ) protrudes past the short-circuit piece ( ), insensitivity to axial or radial play is possible. Furthermore, the measuring device is relatively simple and space-saving in design.
