Claim 17:
18. An ultrasonic surgical instrument, comprising:
(a) a first modular assembly configured to mechanically couple with a second modular assembly in a predetermined alignment, wherein the first modular assembly includes:
(i) a body assembly configured to support an ultrasonic transducer, and
(ii) a transducer power circuit configured to electrically connect to the ultrasonic transducer and a generator; and

(b) an electrical lockout having a first lockout portion positioned on the first modular assembly in electrical connection with the transducer power circuit and configured to sense the predetermined alignment of the second modular assembly relative to the first modular assembly and further sense misalignment of the first and second modular assembly from the predetermined alignment,
wherein the first lockout portion is configured to inhibit powering of the transducer power circuit with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state,
wherein the first lockout portion is further configured to allow powering of the transducer power circuit with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state, and
wherein the first modular assembly is configured to mechanically couple with the second modular assembly in the predetermined alignment relative to each other such that the first modular assembly is configured to be fixed relative to the second modular assembly in the predetermined alignment.
