Abstract: A device and a method for the rotary coupling of optical fibers is disclosed. The coupling device includes a first housing element and a second housing element. The coupling device has a rotation axis around which the first and second housing element can rotate relative to each other. The device also includes a first fiber positioning element for the positioning of a section of a first optical fiber relative to the first housing element, a second fiber positioning element for the positioning of a section of a second optical fiber relative to the second housing element, and a fiber guiding body in which a fiber guiding capillary is constructed. The fiber guiding capillary extends continuously along the rotation axis from a first fiber insertion opening for the reception of an end section of the first optical fiber, to a second fiber insertion opening for the reception of an end section of the second optical fiber.
