This is the feature further than what a simple fluid coupling delivers, which may match rotational speed but isn't going to multiply torque. Fluid-coupling–centered torque converters also commonly include a lock-up perform to rigidly couple enter and output and avoid the effectiveness losses connected to transmitting torque by fluid circulation https://torque-converter-clutch39493.blue-blogs.com/40974183/top-torque-converter-clutch-secrets
