A valve assembly includes a valve body and a bonnet. The valve body has a cylindrical access channel with adjoining at least one radial keyway. At least one coupling cavity adjoins and is out of register with the at least one radial keyway. The bonnet has a cylindrical body with at least one radially extending lug. The at least one lug is configured and sized to be accepted by the at least one radial keyway and to be housed within the at least one coupling cavity when the cylindrical body is twisted so that the at least one lug is out of register with the at least one radial keyway.
