The proposed device is intended for use in motor vehicles and permits a high level of accuracy in measurement and simple and cost-effective manufacture. It comprises a shaft component (12) arranged adjustably in a housing element (21) and a rotating unit (20′) of a rotation angle sensor (2) which can move in relation to the fixed unit (20). The stator element (21) consists of two rounded cusp-shaped subcomponents held with a bracing unit and secured in a stator mount (23). There is a clearance recess between the subcomponents of the stator element. The rotating unit (20′) is a ring-shaped magnet element (24) held by a magnet holder (26,27) connected to the shaft element (12); this arrangement allows the magnet element (24) to move around the stator element subcomponents leaving an air gap (25). The housing element (13) can be constructed in many parts. The stator mount (23) and parts of the multiple-component housing element (13) can be moulded from an electrically conducting long-fibre granulate with 1%-10% by volume stainless steel filaments. This creates a high degree of shielding against electromagnetic influences.

A regulating device comprising an adjustable throttle-valve shaft accommodated in a housing in a subassembly, a stationary sensor subassembly of a angle-of-rotation sensor accommodating a stator comprising two stator components shaped like blunted crescents secured by a stator-tensioning subassembly and accommodated in a stator holder in the form of a cap, a clearance between the stator components, and another sensor subassembly of the angle-of-rotation sensor that rotates around the stationary sensor subassembly, whereby the rotating sensor subassembly is an annular magnet accommodated in a magnet holder, secured by a spacing disk, and attached to the shaft such that the magnet moves around the stator components and leaves an air gap.
