Abstract:
1. An actuator device comprising an actuator housing with a fitting for connecting said actuator to an object, a motor which via one or more transmission elements drives an output actuator shall, wherein said actuator shaft is rotationally disconnectable from said motor, said actuator shaft being rotatable between a first and a second angular position, said first angular position corresponding to said object being in a first condition and said second angular position corresponding to said object being in a second condition, an element for storage of mechanical energy, said element by energy cut-off to the actuator being releasably arranged to be able to displace a nut being prevented from rotating around a longitudinal axis, along a screw thread complementary fitting to said nut, and connected to said actuator shaft, whereby said actuator shaft is rotated between said first and second angular positions.
