Monitoring and control of power or drive couplings in mechanical drive systems is performed using sensors at an interface of the coupling and an overload disengagement component at the coupling. A local sensor and actuation module having a wireless communication port receives signals from the sensors and uses the signals to monitoring a load on the drive coupling. An overload disengagement circuit responsive to the monitored load and provides a disconnect signal responsive to a sensed overload condition, and communicates with the local sensor and actuation module using an Internet of Things (IoT) link, using a blockchain enablement protocol. The local sensor and actuation module provide an override capability in the event of a communication failure of the IoT link.
