1. A surgical instrument, comprising:
(a) a body assembly;
(b) a shaft assembly distally extending from the body assembly and including an acoustic waveguide;
(c) an ultrasonic blade distally extending from the shaft assembly and in acoustic communication with the acoustic waveguide;
(d) a clamp assembly including a clamp arm having a passageway surrounded by an interior surface extending therethrough; and
(e) a coupling assembly defining an axis and including a pin received within the passageway along the axis thereby operatively connecting the shaft assembly and the clamp arm, wherein a first portion of the pin is in contact with the interior surface, wherein a second portion of the pin and the interior surface define a gap therebetween, wherein the coupling assembly is configured to couple the clamp arm relative to the ultrasonic blade such that the clamp arm is configured to selectively move toward the ultrasonic blade from a first configuration through a second configuration toward a third configuration,
wherein the clamp arm is configured to pivot relative to the axis via the coupling assembly with selective movement from the first configuration toward the second configuration, and
wherein the clamp arm is configured to translate relative to the axis via the coupling assembly with selective movement from the second configuration toward the third configuration.
