The invention relates to a rotary actuator having a handle 4, which is rotatable about an axis of rotation 3, and a position sensor system for detecting the rotary position of the handle 4. The handle 4 has, at the end thereof which faces away from an operating side of the handle 4 and consists of an electrically non-conductive material, at a radial distance from the axis of rotation 3, an actuating segment 7 which is made of an electrically conductive material and, forming a capacitor, is opposite a sensor segment 11, 20 of a stationary segment ring 10, 19, which is concentric with respect to the axis of rotation 3 and consists of a plurality of sensor segments 11, 20 which are uniformly distributed on the periphery of the segment ring 10, 19, are spaced apart from one another in the circumferential direction and are made of an electrically conductive material, in a manner axially spaced apart by an air gap 8, wherein a sensor line 13 leads from each sensor segment 11, 20 to evaluation electronics 14.
