The device (10) comprises a base part (12), a rotational part (14) movable relative to the base part about a rotation axis (16), a first linear actuator (18) having a first end (19) and a second end (20), the first end being attached to the base part, the second end being attached to the rotational part at a first anchor point arranged on a first turning axis (21), and a second linear actuator (22a) having a first end (23) and a second end (24), the first end being attached to the base part, the second end being attached to the rotational part at a second anchor point arranged on a second turning axis (25). The first turning axis is arranged at a first distance from the rotation axis, and the second turning axis is arranged at a second distance from the rotation axis, the second distance being different from the first distance.
