The assembly 1 comprises relatively rotatable parts 2, 3 which interfit to retain a torsion element 4, so that relative rotation of the parts changes the strain in the torsion element. The female part 3 has a slightly larger bore diameter than the external diameter of the male part 2 so permitting the male part 2 to be axially receivable in the female part 3. Both parts are hollow and configured as a tubular casing so as to accommodate and retain a torsion element 4. The torsion element 4 is in form of a helical spring. The distal ends of the coiled spring have diametrical protrusions or formations 5 which engage with corresponding diametrical slots 6 formed in respective back walls of the interfitting parts 2, 3. A damping mechanism can be additionally incorporated within the torsion biasing assembly 1 by disposing grease or another suitable viscous substance such as silicone gel between the relatively rotatable surfaces of the interfitting parts 2, 3. |
