Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a force is applied between the assemblies.

Force coupling or torque coupling assemblies, apparatuses, systems, and methods include assemblies that each include superhard contact elements. At least some of the superhard contact elements may be configured to remain in contact with each other when a rotational force and/or a thrust force is applied between the assemblies.

A connector for adjustably connecting an RVDT (rotary variable differential transformer) and a reductor shaft. The connector includes a body defining a bore configured to receive the reductor shaft. The bore has an inner wall and a threaded tightening member which is substantially parallel to a main axis (AA, BB) of the bore. A portion of the body is configured to deform upon tightening of the tightening member such that, when the reductor shaft is received by the bore, the reductor shaft is gripped by at least a portion of the inner wall.

A torque transfer coupler for a roller blind. The torque transfer coupler has a central body securable to an electric motor and includes one or more torque transfer elements engaging the interior of the blind's roller tube. The coupler includes an anti-slip member having one or more resilient portions having a rest position and a deflected position. When, in their rest positions the resilient portions have a dimension larger than the cross sectional area of the roller tube. When in their deflected positions and received within the roller tube the resilient portions engage the interior surface of the roller tube resisting the withdrawal of the torque transfer coupler, and the electric motor secured thereto, from the interior of the roller tube.

A machine element includes individual ring components (10, 12) fastenable to third components, such as axles, shafts, or hubs. One ring component can be actuated toward another ring component in an advancing motion by an adjusting device (18) in an axial direction (Y). An angled force application to the one ring component (10) in a tilted direction (24) that deviates from the axial advancing direction (Y) occurs by the adjusting device (18) for the advancing motion. The ring component that is exposed to the angled force application follows the tilted direction by a contact surface (30) for the contact with the adjusting device (18). In a thread-free segment of the adjusting device (18), the adjusting device has a titled control surface (32). The adjusting device then follows the contact surface (30) with its tilted direction (24) when the adjusting device (18) is actuated.
