Mae'r Cydgysylltwyr yn gyfrifol am ddatblygu rhaglen waith a fydd, yn ogystal â gwella cydlyniant cymunedol, o fudd i gyflawni blaenoriaethau lleol a chenedlaethol mewn sawl ffordd, gan gynnwys trechu tlodi, gwella diogelwch cymunedol a hyrwyddo cydraddoldeb.  Mae cysylltiad cryf hefyd â chyfrifoldeb statudol awdurdodau cyhoeddus penodol i ystyried yr angen i 'feithrin perthynas dda', fel a bennir o dan Ddeddf Cydraddoldeb 2010.
The Co-ordinators have responsibility for driving forward a programme of work which, in addition to improving community cohesion, has multiple benefits for delivering on local and national priorities, including tackling poverty, improving community safety and promoting equality. There is also a strong link with the statutory responsibility of specified public authorities to have due regard to the need to ‘foster good relations’ as set out under the Equality Act 2010.
