This invention relates to a compact spring return actuator, and more particularly to an actuator for emergency reset of a valve in the event of an emergency such as a power outage. The actuator is equipped with differential planetary gear reducers in both the drive shaft (operated by a motor) and the working shaft (operated by an elastic body of the emergency reset assembly), and these differential planetary gear reducers are meshed together. This duality allows the power transmission of the motor and the elastic body to be independent of each other, thereby reducing motor capacity and miniaturizing the components of the power transmission system. Ultimately, this results in a compact spring return actuator that is lightweight and miniaturized as a whole. To achieve the objectives described above, the compact spring return actuator of the present invention is characterized by comprising: a drive shaft that receives power from a motor and rotates; a driven shaft that rotates by means of the drive shaft and opens and closes a valve; a reduction assembly that reduces the rotational force transmitted to the driven shaft, including a differential planetary gear reducer mounted on the drive shaft; and an emergency reset assembly equipped with an elastomer and a working shaft that converts the elastic force of the elastomer into a rotational force for transmission and engagement with the differential planetary gear reducer, for rotating and resetting the valve when the power is disconnected.
