Abstract
A coupling between a direct drive valve motor and a spool for converting rotary-to-linear motion. A bushing is coupled to the spool and defines an opening therein. An end of a shaft carried by the rotor of the motor is received within an opening in the busing. The bushing is outwardly expandable upon the receipt of the end of the shaft to couple the shaft to the spool with minimal frictional forces and near zero backlash.
