The invention relates to an actuator comprising a body part and at least two coaxially mounted cylindrical rotor parts. A first interconnection formed between the first rotor part and the body part, and at least one second interconnection formed between two rotor parts. Each of the first and the second interconnection is provided with at least one cavity formed into one of the inter- connected parts and the other interconnected part is provided with a protrusion movable within the cavity and the actuator is further provided with at least one fluid channel for the at least one cavity of each of the interconnection in order to control a rotational position of at least one of the rotor parts by controlling pressure in the at least one fluid channel of each interconnection. The invention relates also an actuator system. |
