Abstract
An overtravel absorbing drive connection for a servo operated rotary actuated valve having an external shaft means. A crank pin provided on the external portion of the shaft means is engaged on opposite sides thereof respectively by a pair of resilient arms extending from driving hub of a connector attached to the servo output shaft. Continued rotation of the servo output shaft after closure of the valve is absorbed by resilient bending of the connector arms.
