Abstract
An inner barrel shaft is separate from the shaft of the first rotating machine. A first bearing assembly is configured to support the inner barrel shaft. The first bearing assembly is separate from the first rotating machine. An outer barrel includes an outer barrel shaft that is separate from a shaft of a second rotating machine. The outer barrel is configured to be coupled to the shaft of the second rotating machine. The second rotating machine is configured to drive or be driven by the first rotating machine. The outer barrel is fluidically isolated from the inner barrel. The outer barrel is configured to surround the inner barrel. The outer barrel is magnetically coupled to the inner barrel to co-rotate with the inner barrel. A second bearing assembly is configured to support the outer barrel shaft. The second bearing assembly is separate from the second rotating machine.
