Abstract: A wind energy conversion device includes a support frame that pivots on a vertical yaw axis, and a rotor/bushing assembly coupled to the support frame through a governing coupling that permits the rotor/bushing assembly to pivot on a governing axis relative to the support frame. The governing axis is inclined from the vertical preferably by about 30.degree. to provide a substantial gravitational bias of the rotor/bushing assembly toward a normal operating position when wind velocities are below a predetermined threshold. The governing axis also is laterally offset from a drive axis about which the wind rotates a propeller of the rotor/bushing assembly. This facilitates alignment of the rotor/bushing assembly so that the drive axis intersects the yaw axis. As a result, wind induced thrust does not generate a torque about the yaw axis.
