Coupling device for coupling tower segments of a tower of a wind power installation, tower segment, part of a tower, tower, wind power installation and installation method

A coupling device for coupling first and second tower segments arranged relative to one another of a tubular tower of a wind power installation, the coupling device comprising:

• a coupling plate configured to be in contact with abutting regions of the first and second tower segments and arranged with respect to one another, the coupling plate comprising:
• a fastening portion having a first contact surface configured to be arranged on a circumferential surface of the first tower segment, and
• a connecting portion adjacent to the fastening portion and having a second contact surface configured to be arranged on a circumferential surface of the second tower segment and at least one through-opening for the passage of a threaded element, and
• a receiving plate arranged on the connecting portion on an outer surface opposite the second contact surface, the receiving plate comprising at least one receiving element for receiving a counter element configured to be bolted to the threaded element,
• wherein the at least one receiving element is formed coaxially with respect to the through-opening and as an anti-twist protection for blocking the counter element from rotating and preventing bolting to the threaded element.
