Abstract
A coupling for use in a rotary Ball valve having a spherical ball with a passageway therethrough controlling the flow of fluid through the valve. The coupling is particularly suited for use with non-metallic, for example, ceramic, spherical balls which are rotated by torque applied to a metallic actuator shaft extending from the valve body. The coupling includes a plurality of depressions and protrusions formed at the interface of the non-metallic and metallic components. The depressions and protrusions are positioned away from the central axis of the spherical ball. A cushion is interposed between the metallic and non-metallic components to further disperse the force applied to the non-metallic component so that as torque is applied to the shaft the non-metallic component is rotated without breakage thereof.
