1. A forceps comprising:
an inner shaft extending from a proximal portion to a distal portion;
an outer shaft located around the inner shaft, the outer shaft extending from a proximal portion to a distal portion;
a rotational actuator;
a hub rotationally fixed to the rotational actuator at a keyed interface and rotationally fixed to the inner shaft at a first connection and the outer shaft at a second connection different from the first connection, the first connection and the second connection being independent of each other;
an end effector coupled to the distal portion of the outer shaft at a first longitudinal location; and
a shaft pin located proximal of the first longitudinal location, the shaft pin connected to one of the outer shaft and the inner shaft and extending across the outer shaft and extending through an aperture in the other of the outer shaft and inner shaft,
wherein the shaft pin is configured to limit relative rotation between the distal portion of the outer shaft and the distal portion of inner shaft.
