Abstract
A piezoelectric actuator that may include a monolithic frame having an integral bias band that provides a resilient restoring force between a first contact surface and a second contact surface of the actuator that may be used to rotate an adjustment shaft. In some cases, a preload mechanism may also be included with the frame. Such piezoelectric actuators may be used for adjustable optical mounting devices such as optical mounting devices.
