1. An apparatus for coupling a surgical instrument to a surgical robot;
the apparatus comprising:
a first portion configured to attach to an end of an arm of the surgical robot using a plurality of fasteners, the first portion including a first rod extending away from the arm to provide a distal end of the first portion;
a second portion configured to hold the surgical instrument, the second portion including a second rod extending away from the surgical instrument to provide a distal end of the second portion;
a first interface located at the distal end of the first portion;
a second interface located at the distal end of the second portion, the second interface including a receiver having an inward, conically shaped alignment surface and configured to join with the first interface and to align the second rod with the first rod to form an aligned axis; and
a first collar configured to collar the first and second interface to secure the first portion with the second portion, and to slidably adjust along the aligned axis to allow engagement and dis-engagement of the first and second interfaces with each other, wherein an outer surface of the receiver includes a first cam groove configured to receive a cam follower of the first collar and to guide the cam follower to a second cam groove of the first interface.
