Abstract

Apparatus for coupling a piezoelectric motor to a moveable body, the motor having a coupling surface for coupling to the moveable body, the apparatus comprising: at least one elastic element that provides at least a portion of a coupling force for pressing the coupling surface of the piezoelectric motor to the moveable body; and at least one shape memory component that is controllable to change shape and/or phase; wherein the at least a portion of the coupling force provided by an elastic element of the at least one elastic element changes responsive to changes in shape and/or phase of the at least one memory component.
