1. A surgical system, comprising:
an end effector configured to receive a staple cartridge, wherein the end effector comprises:
a first jaw; and
a second jaw rotatable relative to said first jaw between an open configuration and a closed configuration;
a motor;
a rotary input drivable by the motor; and
a rotary output drivable by the rotary input, wherein rotation of the rotary output is configured to effect at least one function of the end effector;
wherein the rotary input and the rotary output are configurable between:
a coupled state in which rotation of the rotary input causes corresponding rotation of the rotary output; and
a slipped state in which the rotary input rotates relative to the rotary output;
wherein the rotary output is to experience a resistive torque in the coupled state, and wherein the rotary input and the rotary output are configured to transition from the coupled state to the slipped state based on the resistive torque exceeding a torque threshold.
