The electric actuator has an electric motor operable to determine the output force generated on an output member by a spring. A drive shaft is arranged to be driven by the electric motor and has two drivers. A non-rotational but axially movable intermediate member is threadly engaged with one driven po part arranged to be driven by driver. The spring is located between the intermediate member and the output member and arranged so that axial movement of the intermediate member is transmitted to the output member so long as the output member is free to move and, when the output member is restrained from movement, generates the output force on the output member upon continued operation of the electric motor.
