Retention of that reciprocal profile with prior arrangements is difficult. By providing the engagement elements supported upon a volume of particles (6, 56, 65, 86, 96, 116, 406, 806, 1402, 2006) which can act as a fluid medium relative displacement between the engaged elements can be achieved. Once displacement into a reciprocal profile is achieved the volume of particles is locked by actuator (4, 84, 94, 114, 404, 804, 904, 2007) pressure and therefore in support of a component resistance to vibration and other factors is significantly enhanced.
