Abstract
In order to position a rotary actuator, a positioning device is coupled to the actuator. The positioning device has a coupling shaft and springs which respectively surround top and bottom portions of the shaft and are coupled thereto by respective coupling rings. The springs apply oppositely directed torques to the shaft such that one spring urges the shaft in a clockwise direction towards a stop position and the other spring urges the shaft in a anticlockwise direction towards that stop position. The stop position corresponds to an intermediate rotary position of the actuator.
