You can contruct it yourself like this:
for key, value in self.fields.items():
value.widget.attrs.update({'class': 'form-control'})
if value.help_text:
django_id_for_label = self.auto_id % key # self.auto_id == 'id_%s'
my_id_for_label = '{}Help'.format(django_id_for_label)
value.widget.attrs.update({'aria-describedby': my_id_for_label})
