A coupling between the motor of a direct drive valve and a spool for converting rotary-to-linear motion. The coupling includes a split bushing with spring means encircling the same and urging it together. The end of a shaft carried by the rotor of the motor is inserted into an opening in the split bushing to urge it outwardly against the spring.
