Claim 2:
3. The actuator according to claim 1, wherein
the first harmonic gearing has a first wave generator that can be driven by at least one first sub-drive, wherein the first wave generator is located inside a first flex spline that is non-rotatably connected to the first transmission housing, wherein the first flex spline has a first set of external teeth, and
the second harmonic gearing has a second wave generator that can be driven by at least one second sub-drive, wherein the second wave generator is located inside a second flex spline that is connected to the second housing for conjoint rotation, wherein the second flex spline has a second set of external teeth, and
the at least one coupling element forms an integral circular spline or a multi-part circular spline, and wherein the circular spline contains one or more sets of internal teeth, which correspond to the first and second sets of external teeth.
