The invention relates to a transmission for a spring return actuator The transmission comprises a drive pinion (2) associated with the actuator, an intermediate pinion (5) meshing with the drive pinion (2), an output shaft (3) with a clutch (4) for a final control element, and two wheels (6, 7) disposed on the same spindle. The wheels (6, 7) have respective external toothing (8, 9) and a respective rotatably mounted hub (10, 11) which extends with the interposition of an annular gap around the output shaft (3). The drive pinion (2) is in engagement with the external toothing (8) of one of the two wheels. The intermediate pinion (5) engages in the external toothing (9) of the other wheel. A clutch sleeve (14) is disposed in the annular gap between the output shaft (3) and the wheels (6, 7), is releasably connected to the output shaft (3) and is in positive engagement with the hub (10, 11) of one of the wheels (6 or 7). The directlon of rotation of the output shaft (3) can be changed by changing the clutch sleeve (14). - Fig. 1.
