An apparatus (B) controls rotation of an annular member (36) relative to top and bottom housings (12, 10). The bottom housing (10) includes a disk (110) extending radially and terminating in a cylindrical portion (112) having circumferentially spaced slits (212). A wedge (16) abuts with the cylindrical portion (112) and is moved radially between first and second positions by an axially moveable piston (14), with the wedge including an angle surface (340) which interfaces with an angled surface (520) of the piston (14) through a plurality of balls (18). The disk (110) and the cylindrical portion (112) are formed as a single component of material having sufficient material strength and yield to allow engagement and disengagement of the cylindrical portion (112) with the annular member (36). The wedge (16) is slideable between an axial surface (250) of the disk (110) and a guiding flange (450) of the top housing (16). Un aparato (B) controla la rotación de un miembro anular (36) en relación con los alojamientos superior e inferior (12, 10). El alojamiento inferior (10) incluye un disco (110) que se extiende radialmente y termina en una porción cilíndrica (112) que tiene hendiduras (212) circunferencialmente separadas. Una cuña (16) hace contacto con la porción cilíndrica (112) y se mueve radialmente entre las posiciones primera y segunda mediante un pistón axialmente móvil (14), con la cuña que incluye una superficie angulada (340) que se interconecta con una superficie angulada (520) del pistón (14) a través de una pluralidad de balines (18). El disco (110) y la porción cilíndrica (112) se forman como un solo componente de material que tiene suficiente resistencia y deformación de material para permitir el acoplamiento y desacoplamiento de la porción cilíndrica (112) con el miembro anular (36). La cuña (16) es delizable entre una superficie axial (250) del disco (110) y un reborde guía (450) del alojamiento superior (16).
