A coupling device includes first and second relatively rotating members mounted about a common axis and first and second lines fixed between the first and second members. The first line is adapted to wrap around the first member in a first direction and around the second member in a second direction, opposite the first direction, the second line is adapted to wrap around the first member in the second direction and around the second member in the first direction. A guide is revolvably mounted to the first and second members for translating the first and second lines between the first member and the second member as the first and second members rotate relative to each other.
