Zusammenfassung:	An example apparatus includes a valve body defining a fluid flow passageway between an inlet and an outlet, a cage disposed in the fluid flow passageway, a plug disposed in the cage, a retainer collar coupled at an end of the plug, where an exterior surface of the retainer collar includes a first engagement surface having a first non-circular cross-section, and an anti-rotation collar coupled at an end of the cage, where the anti-rotation collar has a second engagement surface defining an aperture to receive the retainer collar, where the aperture has a second non-circular cross-section, where the engagement surfaces interact to inhibit rotation of the retainer collar and the plug.
