1. An electric fail-safe actuator comprising:
a speed reducer/gear assembly housing arranged between one or more electric motors and a rotation to linear transformer comprising a roller or ball nut and a screw, or a nut and a roller or ball screw,
wherein the speed reducer/gear assembly housing is connected to an actuator housing via a counter hold release mechanism, allowing the speed reducer/gear assembly housing to co-rotate with a rotational side of the rotation to linear transformer when the counter hold release mechanism is released.
