Abstract:
1. A torque-transmitting assembly comprising: a) a female coupling member with a bore; b) a radially flexible member, received within the bore, defining a hollow shape with an opening, the radially flexible member being made of super-elastic alloy; and c) an elongated shaft member made of a super-elastic alloy, received within the opening, wherein forcing the radially flexible member onto the shaft causes the radially flexible member to contact the shaft, inducing a super-elastic activation in the shaft and further induces a super-elastic activation of the radially flexible member that urges the shaft and radially flexible member into surface-to-surface contact, securing the members together in a fixed relative position.
