The adjustable support includes a base including a bore having an open mouth; a screw being movable received in the bore while having a free end configured to project past the open mouth of the bore; and a driver being arranged in driving engagement with the screw, whereby a rotation of the driver results in a linear movement of the screw along the longitudinal extension of the bore. The driving arrangement includes a driver actuator arranged to be driven by the motor. Further, a method of orienting an element relative to a reference plane is provided.
