Abstract
An electric actuator for a final controlling device having a safety actuator function for positioning an actuating element, (e.g. a valve element of, for example, a process-technical plant). The electric actuator can include an electric motor configured to provide a torque for actuating the actuating element. The electric motor can include a motor shaft configured to deliver the torque, an output shaft configured to transmit the torque from the electric motor to the actuating element, and an electromagnetic and/or currentlessly uncoupling coupling (e.g. electromagnetic and/or currentlessly uncoupling clutch) configured to provide and/or interrupt a torque-transmitting connection between the motor shaft and the output shaft. The output shaft, the motor shaft and the coupling can be arranged coaxially to one another.
