The housing comprises a base part 18 and a cover part 20 which are fixedly joined together. In the embodiment shown in Figs. 1, 3 and 4 the drive member has parts 72 pivotably mounted thereon. The pawls are biased outwardly by springs 86 and have teeth on their radial outer surfaces which engage with teeth on surface 40 of the housing. These teeth are canted over such that rotation of the housing in one direction forces the pawls inwardly to allow ratcheting whilst rotation in the opposite sense provides drive to member 48. Fingers 68 limit rotation of the pawls. The drive member retains the tool member 12 by fingers 56 that give an inwardly tapering bore. The interior of the housing may be filled by a lubricant. Fig. 9 shows an alternative construction of pawls 72. Fig. 10 shows a further embodiment with a ring 94 pivotally attached to the drive member 48. The ring has fingers 96 which have their outer ends chamfered to give an edge. The length of the fingers is slightly greater than the distance between member 48 and the housing so that they are canted over. Fig. 12 shows fibres 106 bonded to a base 108 which is bonded to member 48. The fibres are canted and engage a screen on a suitable backing 112 which is attached to surface portion 40 of base 18. These latter two embodiments also provide an override feature to limit applied torque to a predetermined level. The handle assembly is preferably made from polymers such as the polycarbonates, the long-chain polyamides, the polyesters, the polyolefins, the vinyl and vinylidene resins and the fluoroplastics which may be reinforced by glass fibres.
