A metallic coupling for a drive shaft includes a first cylindrical flange extending axially along a center axis and a second cylindrical flange extending axially along the center axis and spaced axially from the first cylindrical flange. The metallic coupling also includes a first plurality and a second plurality of connectors. Each connector of the first plurality of connectors extends from the first cylindrical flange to the second cylindrical flange and are spaced circumferentially apart from each other about the center axis. Each connector of the second plurality of connectors also extends from the first cylindrical flange to the second cylindrical flange and are spaced circumferentially apart from each other about the center axis. The second plurality of connectors are radially inward from the first plurality of connectors relative to the center axis. An annular gap is radially between the first plurality of connectors and the second plurality of connectors.
