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). 一种装置(B)控制一环状构件(36)相对于顶框和底框(12,10)的转动，底框(10)包括径向延伸且终止于一圆柱部(112)的一碟片(110)，圆柱部(112)有圆周相隔狭缝(212)。一楔子
