1. An actuating spindle drive for adjusting a pivotable vehicle flap, the actuating spindle drive comprising
a housing;
a spindle rod rotatably mounted in the housing;
a first coupling element for driving a rotational movement of the spindle rod; and
a torque-limiting device arranged between the first coupling element and the spindle rod for limiting the torque transmitted from the first coupling element to the spindle rod, the torque-limiting device comprising:
an adapter sleeve arranged at a first end of the spindle rod in a rotationally fixed manner, and
a first tolerance element arranged radially between the spindle rod and the first coupling element, the first tolerance element being rotationally fixed to one of the first coupling element and the adapter sleeve,
wherein the one of the first coupling element and the adapter sleeve has at least one first retaining element,
wherein the first retaining element is a projection having a first lateral support surface and a second lateral support surface,
wherein the first retaining element prevents a rotational movement of the first tolerance element relative to the one of the first coupling element and the adapter sleeve by contact between the first retaining element and the first tolerance element.
