1. An electromechanical actuator, comprising an electrical motor, a first rotational member being in driving connection with the electrical motor, a second rotational member being connected to the first rotational member by means of a plurality of rolling elements such that the first rotational member and the second rotational member together form a ball ramp mechanism, and a return spring pressing the first and second rotational members towards each other, wherein the ball ramp mechanism is configured to allow for mutual rotation of the first and second rotational member up to a first torque of the electrical motor, and to allow for axial separation of the first and second rotational members at a second torque of the electrical motor.
