Lovejoy provides drop-in replacement couplings for GE and Vestas turbines

The electrical isolation joint comes from the feature highlighted in red. 

The Lovejoy drop in replacement couplings for GE and Vestas wind turbines provide a bolted electrical-isolation joint that prevents stray or eddy currents from damaging gearbox bearings. The design also eliminates the bonded joints that can be prone to low-temperature delamination.

In addition, the design includes an anti-flail feature to confine the center member in the event of a failure. The feature was first used by the petrochemical industry to eliminate auxiliary-equipment damage in the case of a drivetrain issue. The couplings will interface with existing gearbox and generator hubs.

The Lovejoy coupling has replaced and upgraded the original Vestas coupling.
