Abstract

An embodiment of a coupling device is configured to be disposed in a borehole string in a borehole in a subterranean region. The coupling device includes a coupler body having a longitudinal axis, the coupler body including an elongated shaft extending along the longitudinal axis and configured to carry loads through the coupling device, a stiffness control device connected to the elongated shaft, the stiffness control device configured to adjust a bending stiffness of the coupler body, and an actuator configured to cause the stiffness control device to adjust the bending stiffness of the coupler body.
