A valve apparatus includes selectively releasable engagement apparatus for operatively connecting an actuator to a valve body of a valve having an operating member extending outwardly from the valve body along an axis of the operating member are provided. The engagement apparatus includes a latch arm extending from the valve side of a base, rather than the actuator side of the base. A plurality of protrusions on the valve body and corresponding mating receptacles on the base resist torque forces on the base. A slot in the base adjacent an edge of the latch arm provides passage for tooling used in forming the base. A base in the form of an adapter allows attachment of an actuator not having a selectively releasable engagement apparatus to a valve body that does include a selectively releasable engagement apparatus.
