Compensating coupling, comprising: a first coupling member made in one piece from fibre composite material and having a first flange portion for attachment to a first drive element , a diaphragm portion that is corrugated and extends radially outwardly from the first flange portion , a second flange portion and a tube portion extending axially from an outer circumference of the diaphragm portion to the second flange portion , a second coupling member made in one piece from fibre composite material and having a first flange portion for attachment to a second drive element , a diaphragm portion that is corrugated and extends radially outwardly from the first flange portion , a second flange portion and a tube portion extending axially from an outer circumference of the diaphragm portion to the second flange portion , and connecting elements connecting the first coupling member and the second coupling member at their second flange portions , wherein the corrugated diaphragm portions are spaced apart from each other in axial direction by the tube portions , characterised in that each of the tube portions has two or more recesses that are spaced from each other in circumferential direction by non-recessed portions , said two or more recesses of the tube portions being axially spaced apart a from the diaphragm portions , wherein the recesses are arranged in such manner that in a first relative position of the first coupling member and the second coupling member the recesses of the first coupling member face the recesses of the second coupling member so as to form together apertures for access to an interior of the coupling , and in a second relative position the recesses of the first coupling member and of the second coupling member are offset in circumferential direction and face the non-recessed portions , respectively. a first coupling member made in one piece from fibre composite material and having a first flange portion for attachment to a first drive element , a diaphragm portion that is corrugated and extends radially outwardly from the first flange portion , a second flange portion and a tube portion extending axially from an outer circumference of the diaphragm portion to the second flange portion , a second coupling member made in one piece from fibre composite material and having a first flange portion for attachment to a second drive element , a diaphragm portion that is corrugated and extends radially outwardly from the first flange portion , a second flange portion and a tube portion extending axially from an outer circumference of the diaphragm portion to the second flange portion , and connecting elements connecting the first coupling member and the second coupling member at their second flange portions , wherein the corrugated diaphragm portions are spaced apart from each other in axial direction by the tube portions , characterised in that each of the tube portions has two or more recesses that are spaced from each other in circumferential direction by non-recessed portions , said two or more recesses of the tube portions being axially spaced apart a from the diaphragm portions , wherein the recesses are arranged in such manner that in a first relative position of the first coupling member and the second coupling member the recesses of the first coupling member face the recesses of the second coupling member so as to form together apertures for access to an interior of the coupling , and in a second relative position the recesses of the first coupling member and of the second coupling member are offset in circumferential direction and face the non-recessed portions , respectively. <EOS>
